Nothing compares to him after all

AND it's all back on, folks: Sinead O'Connor has revealed she is back with her "cave man" husband, just days after announcing plans to divorce.

The Nothing Compares 2 U singer, 45, announced last week that she was divorcing her fourth husband Barry Herridge just 18 days after getting hitched on December 8.

The pair tied the knot in the back of a pink Cadillac at the Little White Wedding Chapel (the same spot where Britney Spears and Jason Alexander tied the knot in 2004) on the same day as her 45th birthday.

O'Connor said she was calling an end to her fourth marriage because it was like "living in a coffin".

She claimed "intense pressure" from Herridge's family had contributed to their split, and that the marriage ran into trouble when she took her drugs counsellor husband on a hunt for cannabis around Vegas.
